Abstract: Techniques for selecting universal hyper parameters for use in a set of machine learning models across multiple computing environments include detection of a triggering condition for tuning a set of universal hyper parameters. The set of universal hyper parameters dictate configuration of the set of machine learning models that are independently executing, respectively, in the multiple computing environments. Based on the detected triggering condition, a first subset of universal hyper parameters from the set of universal hyper parameters are altered to generate a second set of universal hyper parameters. The second set of universal hyper parameters are applied to the set of machine learning models across the multiple computing environments.

Abstract: Various methods and systems for propagating identity information in a composite application are presented. State data of a composite application, as executed for a particular entity, may be transferred to and stored by a computer-readable storage medium. The state data may include a portion of a set of subject information linked with the entity. A security attribute of the subject may not be present in the portion of the set of subject information in the state data transferred to the non-transitory computer-readable storage medium. After a period of time, such as an hour or a day, the state data of the composite application as executed for the entity may be retrieved and the security attribute of the set of subject information linked with the entity may be determined The composite application may then continue to be executed for the entity.

Abstract: Embodiments of the invention include techniques for processing messages transmitted between computer networks. In some embodiments, messages such as requests and responses for various types of web services, applications, and other web content may be transmitted between multiple computer networks. One or more intermediary devices or applications, such as a proxy server implemented within a physical or logical subnetwork, may receive, process, and transmit the messages between the communication endpoints. In some embodiments, a proxy server may be configured to operate within a subnetwork of an internal computer network, exposing various web applications and/or services of the internal computer network to external computer networks. Such a proxy server may select specific policies for processing messages based on various message characteristics and the current point in a predetermined processing flow for the message. After selecting the specific policies to be applied to the message, the proxy server may process the message in accordance with the policies and forward the message to its intended destination.

Abstract: Methods, systems, and devices are described for identifying compatible web service policies between a web service and a web service client. A first and second set of one or more identifiers linked to web service policies supported by the web service and web service client may be calculated, respectively. The sets of identifiers may be compared. Using the comparison, a number of common identifiers present in the first set of one or more identifiers linked to the web service policies supported by the web service and the second set of one or more identifiers linked to the web service policies supported by the web service client may be identified. Using the number of common identifiers, a web service policy of the web service compatible with a web service policy of the web service client may be identified.

Abstract: Techniques for improving system performance based on data characteristics are disclosed. A system may receive updates to a first data set at a first frequency. The system selects a first storage configuration, from a plurality of storage configurations, for storing the first data set based on the first frequency, and stores the first data set in accordance with the first storage configuration. The system may further receive updates to a second data set at a second frequency. The system selects a second storage configuration, from the plurality of storage configurations, for storing the second data set based on the second frequency, and stores the second data set in accordance with the second storage configuration. The second storage configuration is different than the first storage configuration.

Abstract: A model analyzer may receive a representative data set as input and select one of a plurality of analytic models to perform the analysis. Before deciding which model to use the model may be trained, and the trained model evaluated for accuracy. However, some models are known to behave poorly when the training data is distributed in a particular way. Thus, the cost of training a model and evaluating the trained model can be avoided by first analyzing the distribution of the representative data. Identifying the representative data distribution allows ruling out use of models for which the distribution of the representative data is unsuitable. Only models that may be compatible with the distribution of the representative data may be trained and evaluated for accuracy. The most accurate trained model whose accuracy meets an accuracy threshold may be selected to analyze subsequently received data related to the representative data.

Abstract: In one set of embodiments, methods, systems, and apparatus are provided to attach one or more service policies to resources in an enterprise by receiving a first service policy, receiving a first policy attachment that identifies one or more policy attachment attributes of resources in the enterprise, and generate a first global policy attachment that references the first policy attachment and the first service policy. The method can include receiving a request to access a resource including an attribute that matches one of the policy attachment attributes. The method can include determining that the first service policy is an effective policy for the resource based on the matching resource attribute with the policy attachment attribute. The method can include controlling access to the resource responsive to the request using the effective policy.

Abstract: Techniques are disclosed for dynamically switching user identity when generating a web service request by receiving, at a client application, an invocation of a web service, the invocation associated with a first authenticated user identity of a first user, identifying a second user identity, verifying that a switch from the first user identity to the second user identity is permitted by switching rules, including the second user identity in a service request when the switch is permitted, and communicating the service request to the web service. The switching rules can include associations between initial user identities and permitted user identities. Verifying that a switch is permitted can include searching the associations for an entry having an initial user identity that matches the first authenticated user identity and a new user identity that matches the second user identity, wherein the switch is permitted when the entry is found.
